Voters in the crucial swing state will also decide key questions on their — and our — climate future.

In four days, Pennsylvania will become just about the most important place on Earth.
It is unlikely that either Kamala Harris or Donald Trump can reach the White House without carrying the Keystone State; winning Pennsylvania bumps either’s odds of prevailing in the whole election to over 90%, according to polling analyst Nate Silver’s models. The state will also play a deciding role in control of the U.S. House and Senate, which in turn will help or hamper the next president’s agenda. America’s domestic trajectory, its foreign policy decisions, and even its allies and enemies could all come down to the whims of the state’s 8.9 million registered voters.
But Pennsylvanians have other important choices to make on their ballots, too. “Pennsylvania is a major energy state, and its decisions — regardless of what type of energy it is — have a huge impact on America’s energy portfolio,” John Qua, the campaign manager of Lead Locally, which is supporting 17 down-ballot candidates in the state, told me.
As the nation’s second-biggest gas producer after Texas and third-biggest coal producer after Wyoming and West Virginia, Pennsylvania also holds the distinction of being the fifth-largest greenhouse gas-emitting state in the nation. Its state legislature hasn’t passed new climate legislation since 2008, in large part because of the influence of the fossil fuel industry over local politics. The American Petroleum Institute donates more to Pennsylvania lawmakers than those in any other state, and while fracking isn’t the decisive local issue it’s made out to be in the popular consciousness, it still employs around 100,000 people — more than made the difference in deciding the 2020 election in the state. (Harris notably reneged on her 2019 pledge to ban fracking if elected in an apparent overture to Pennsylvanians, although the state’s imperiled Democratic senator, Bob Casey, has been hammered by his Republican challenger over her prior position.)
Pennsylvania has a Democratic governor, Josh Shapiro, until at least 2026, and Democrats hold slim control over the state House of Representatives by a margin of 102 to 101. The ambition this cycle is to keep the state House and flip the Republican-held state Senate. Picking up three seats there would earn Democrats a governing trifecta, with a tie-breaking vote going to Democratic Lt. Gov Austin Davis. Flip four seats, and they’d have the majority.
But “if you asked me to bet you $10 that the Democrats would win, I wouldn’t take the bet,” David Masur, the executive director of PennEnvironment, a green research and advocacy group that works in the state, told me. “I think it’s just a long shot.”
The path to winning the state Senate and achieving a governing trifecta clearly runs through three districts. The first and easiest pickup is in SD-15, around the state capital in Harrisburg, where the “map is much friendlier to Democrats,” according to Masur. The party would then need to win a competitive seat in SD-37, in the Pittsburgh suburbs, which has tilted blue recently and also seems theoretically within reach. But things get trickier in SD-49, Democrats’ “white whale” district in Erie County, which President Biden won by 2 points but where Republican senator Dan Laughlin remains well-liked. To wrest back the chamber, in other words, the Democrats would “have to run the table,” Masur said. “I don’t even think there’s another race where you could go, ‘Oh, they could get the majority by winning this other seat.’ There’s nowhere else to go. They have to win those three.”
Because of recent redistricting, the climate groups working in the state are cautious about getting their hopes up too high. “Flipping the [state] Senate, which is currently held by Republicans, might be a two-cycle endeavor with these new maps,” Lead Locally’s Qua said. This doesn’t necessarily mean all is lost: Even maintaining control of two of the three levers of government in Pennsylvania would be a victory, and Democrats this summer managed to garner enough bipartisan support to pass legislation to bring solar panels to state schools.
But the stakes — and promises — of a trifecta feel crucial and tantalizingly close. According to a recent analysis by PennEnvironment, Pennsylvania is 48th in the nation for the percentage growth of total solar, wind, and geothermal in the past decade, and 46th in the nation for the percentage of growth in total solar over the past five years, generating less than its neighbors New Jersey, Maryland, and Ohio. “The fossil fuel industry is extremely moneyed and extremely influential, and it’s created a political reality where it’s very difficult to move good climate and clean energy policy forward in Harrisburg,” Flora Cardoni, PennEnvironment’s deputy director, told me. Climate obstructionists in the state Senate often refuse to call up good environmental policies for votes, leaving the state with “no laws on the books that require utility companies in Pennsylvania to increase the amount of clean renewable energy that they provide to their customers” which is “a huge impediment to progress.”
It’s not as if Democrats aren’t ready to go — they are. Shapiro is sitting on a two-bill plan for tackling climate change in the state. One would boost renewable energy to 35% of Pennsylvania’s total generation by 2035, which Cardoni described as “a huge step in the right direction, although we need to do much more.” The second bill would make polluters pay for their carbon emissions and spend the resulting money on clean air, water, and energy efficiency projects — essentially, a backup plan for if the state’s attempt to join the Regional Greenhouse Gas Initiative fails. (Owing to a question of constitutionality, RGGI is in limbo with the state’s Supreme Court.)
So, in a sense, you have to go for it. “Yeah, they’re really hard races,” admitted Caroline Spears, the executive director of Climate Cabinet, which is supporting 26 candidates in the state. “But if you win,” she added, “you win the fifth-largest greenhouse gas emitter in the country.” While she was loath to “compare our states against each other,” Spears pointed out that Pennsylvania’s emissions are about two and a half times those of Arizona, which makes it a much bigger opportunity for reductions.
Perhaps the most important point: No one really knows what’s going to happen. Not only are organizers working with new maps in the state due to 2022 redistricting, but state-level races also rarely attract substantial enough polling to make reliably predictive guesses, especially when there are so many toss-ups and razor-thin margins. Adding to the trickiness, Pennsylvania is one of the few states where residents still appear willing to split their tickets; in 2020, ticket-splitting between the president and the state Legislature was up to 15 points in places, which is part of why Climate Cabinet has targeted races in the state with margins of up to 10 points that other groups wouldn’t touch. “Folks have been like, ‘the Pennsylvania Senate’s not doable.’ That’s the word on the street,” Spears told me. “But I think people are forgetting a little bit that that was also the word on the street about the Minnesota Senate and the Michigan legislature,” which flipped during the 2022 midterms.
What’s encouraging is that Pennsylvania voters — contrary to their image of being fracking obsessives — have been curious or even enthusiastic about pivoting to clean energy when organizers have spoken with them. Following Winter Storm Elliott in 2022, which caused outages across the state, many residents now “recognize that the grid is outdated,” Julia Kortrey, the deputy state policy director at Evergreen Action, a national climate advocacy group, told me. There’s an acknowledgment among many that “the status quo is not working.”
As in many parts of the country this year, local races in Pennsylvania are mainly focused on battles over education, abortion access, immigration, and crime, not necessarily clean energy. But often, climate-related issues are bubbling just under the surface. “I’m not going to go up to someone’s door and ask ‘What issue is on your mind today?’ and have them say, ‘I’m really worried about the PM2.5 concentration or the Mauna Loa CO2 readings,’” Spears told me. “But if they’re like, ‘The cost of living is too high,’ I’m going to have a conversation about home insurance.”
A particularly good example of this is playing out in one of Pennsylvania’s U.S. House races, which will help determine the ultimate makeup of Congress. In the Lehigh Valley, Democratic Representative Susan Wild is attempting to hold off her Republican challenger, state Representative Ryan Mackenzie, who voted against the school solar bill and the state’s clean water act. Wild had been particularly instrumental in helping to replace lead pipes in the area, and she’s made her leadership on the issue prominent in her campaigning. “The Bipartisan Infrastructure Law and lead pipe removal can seem very — I don’t want to say national, but it can be hard to visualize,” Nate Fowler, the regional campaigns director of the League of Conservation Voters, told me. “But for voters in this part of the Commonwealth, it’s easy for them to understand why this is so important.”
It won’t be until after the dust from Tuesday settles — when Pennsylvania’s 19 electoral college votes have been allocated, and its U.S. House and Senate races decided — that national attention will turn to the consequences of the state’s down-ballot races, if it ever does. But whether Democrats run the table or Republicans eat into their opponents’ grip on the legislature, Pennsylvania’s elections will be pivotal to the nation’s greater evolving energy story.
“So much of what we can accomplish in Pennsylvania will lay the groundwork for what is accomplished across the country,” Kortrey, of Evergreen Action, said. “I tell folks, ‘If we can do it in Pennsylvania, we can do it anywhere.’”

Current conditions: South Korea’s heat wave has killed at least 16 people after the southeastern city of Yangsan recorded an all-time national temperature high of nearly 109 degrees Fahrenheit • Washington authorities arrested a man suspected of arson as the Pacific Northwest state struggles to contain wildfires around Spokane • Typhoon Dolphin intensified into a Category 4 storm as it barrels toward southern Japan, where the ongoing heat wave has killed three female lions at a Tokyo zoo.
The United States could reach a deal with Iran as early as today to reopen the Strait of Hormuz to commercial shipping, Treasury Secretary Scott Bessent said. When asked during a Tuesday appearance on CNBC whether the agreement would allow Tehran to charge a toll to oil tankers, Bessent said the pact would include “freedom of movement.”
The announcement came as President Donald Trump faced a particularly grim economic milestone. Thanks to inflation from the Iran War, the price per gallon of diesel in the U.S. has averaged $4.09 since Trump returned to office in January 2025, according to a Financial Times analysis of Energy Information Administration data. That compares to $4.08 during Biden’s four years in office, when the Ukraine war triggered a price shock on diesel.
When the Trump administration brokered an $80 billion deal to support construction of at least 10 more Westinghouse AP1000 reactors in the U.S., the agreement came with a measure that would allow the federal government to request that the company’s owners offer shares of the legendary developer behind much of the American nuclear fleet on the stock market. It now appears that won’t be necessary. Last week, Westinghouse, a co-venture between Canadian uranium giant Cameco and Toronto-headquartered investment giant Brookfield, filed confidential paperwork with the U.S. Securities and Exchange Commission, laying the groundwork for a possible IPO.
The move came just two weeks after Holtec International, another long-standing stalwart in the industry that’s looking to play a central role in the next U.S. reactor buildout, filed its own S-1 paperwork with the SEC. At present, retail investors have limited options to bet on the nuclear renaissance. Startups such as X-energy, Oklo, and Hadron Energy — none of which has yet built a reactor or won Nuclear Regulatory Commission approval of its design — have dominated the market. Established firms such as the nuclear utility Constellation Energy, fuel maker Centrus Energy, and GE Vernova, whose joint venture with Japanese conglomerate Hitachi is a leading reactor developer, have also benefited. But Westinghouse and Holtec would be among the most serious “pure play” contenders on the market with real balance sheets.
British Prime Minister Andy Burnham took power last month after Labour leader Keir Starmer stepped down amid plummeting support within his own party, clearing the way for the populist former Manchester mayor’s democratic socialist reforms. Among the changes Burnham is expected to make on energy is giving the government an even greater role in developing fusion energy. “Because Burnham is committed to greater public control over utilities like energy, but within existing fiscal rules, his impact on fusion is likely to be about governance and ownership structures — for example stronger public or community stakes in fusion projects and more explicit links to regional development — rather than changing the headline national targets for fusion deployment themselves,” analyst Michael Heumann wrote in The Fusion Report.
It’s the type of intervention for which Japan’s fusion industry is pining. As you may recall, Japan’s conservative new “Iron Lady” Prime Minister Sanae Takaichi is going all in on reviving her country’s nuclear industry. But the FT reports that Japan’s fusion industry is now lobbying for more government support to get off the ground.

Dominion Energy’s Coastal Virginia Offshore Wind project is progressing toward coming online by the end of next year. The timeline for the 2.6-gigawatt facility off Virginia’s shores to install its 176th and final turbine pushes back the start date from early 2027. But Dominion said the schedule “reflects additional contingency for weather, vessel maintenance, loadout operations, and extended jacking activities, rather than changes to the base turbine installation rate, which has been two days per turbine so far,” according to offshoreWIND.biz. The update comes after Trump conceded defeat in his battle to use the Department of Justice to wrestle back federal permits issued to offshore wind projects under the previous administration, my colleague Emily Pontecorvo wrote in June.
On Tuesday evening, meanwhile, 10 judges on the U.S. Court of Appeals for the District of Columbia Circuit upheld an earlier injunction that said the Environmental Protection Agency could not cancel $20 billion in climate grants, ruling in a split decision that recipients should have access to the funds.
Renewables made up 54.1% of Spain’s electricity generation in July — and it’s even higher when you count Spaniards who generated solar at home for self-consumption. That’s according to the latest data the national grid operator Red Electric de España published Tuesday. Generation from renewables surged nearly 6% year-over-year to a record 14,699 gigawatt-hours last month, according to Renewables Now. Solar made up by far the largest share for the fourth consecutive month, accounting for more than 28% of the mix in July.

I’m always fascinated by the parallels between Cuba and Puerto Rico, which — despite shared colonial histories and struggles — took divergent paths in the mid-20th Century, only to both end up with aging grids that can’t keep the lights on. I was reminded of conversations I have had with Boricuas who have spent nights sleeping on balconies and porches when the electricity is out, leaving air conditioners and fans idled on hot nights. In Cuba, that’s now happening en masse as the summer heat collides with the ongoing U.S. oil embargo. “Things are only getting worse. Tomorrow it’ll collapse again ... and we’ll be back to sleeping on the Malecón,” Alexey Ríos García told the Associated Press as he used a piece of yellow foam as a pillow to cushion his head from the tough concrete.
What’s next for electric cars? There’s no consensus.
Here’s the good news on electric cars in America: Sales in the second quarter of 2026 rose by 14% compared to the first quarter, which itself was an improvement on the preceding quarter. And here’s the bad: Even those good-looking Q2 sales numbers this year represent a 20% decrease from the same period in 2025.
Welcome to a confused moment in EV history. Electric vehicle sales in this country grew at a decent rate through the early part of the 2020s — right up until they fell off a cliff last fall when the federal tax credit disappeared and cars became $7,500 more expensive overnight. EVs have begun to recover in the intervening months, especially as Americans look for some respite from high gas prices. Yet the lineup of available EVs for them to purchase has been weakened by endless volatility. Car companies struggle to keep up with Chinese competitors abroad and the Trump administration’s relentless attacks on electric vehicles here. Meanwhile, EV makers have shifting visions of what they want electric cars to be.
In the long run, nothing has changed. The automotive industry is headed in one direction: toward a future dominated by battery-powered electric vehicles. But in the short run, even as EVs are setting sales records in dozens of countries and approaching 30% of the global car fleet, it feels like everyone involved in trying to sell EVs to Americans is driving in a different direction.
Just take a quick accounting of the players. At the start of the decade, Ford pinned its hopes on the F-150 Lightning pickup truck and the Mustang Mach-E, but never figured out how not to lose money on them. Last year, the company then blew up plans for its second-generation EV to go back to the drawing board. It stood up a skunkworks team at a far-flung California factory to learn how to slash manufacturing costs and make a mid-size electric truck in the $30,000s, set to emerge from the shadows next year.
Its Detroit rival, GM, looked to be in better shape. It bet its battery-powered fortunes on the Ultium platform that would underpin many vehicles across its lineup. In doing so, it rolled out a more ambitious lineup than Ford: Not just the Chevy Silverado, Blazer, Equinox, and Bolt, but several well-received Cadillac models that breathed some life into that atrophying brand.
In 2024, GM phased out the Ultium name, seemingly to make room for the next-generation architecture to follow. And then things started to get a little rocky. The Chevy Bolt, a hero of the late 2010s era of EVs, returned just in time to be canceled so GM could build more gas-guzzling Buick crossovers. General Motors is now stuck in a wait-and-see on battery power. It may update its existing EVs, particularly the Equinox, but reportedly has no plans to expand its electric offerings until at least 2030 — when, perhaps, some of the dust of the Trump presidency has settled.
GM’s fortunes look rosy next to those of Stellantis, the global giant that owns car brands like Jeep, Dodge, Chrysler, and Ram. Like competitors Ford and GM, Stellantis has had to take on eight-figure losses as it rejiggers its business to try to compete in the electric future. But unlike the Detroit duo, it has no particular success story even to hang its hat upon. Jeep EVs have been a struggle, and the planned Ram EV pickup never even saw the light of day. Now the great electric hope for pickup trucks is the planned Ram extended-range EV, a truck that would carry a gasoline engine simply to act as an onboard generator that recharges the battery.
Among Japan’s legacy automakers, the surprising insurgent is Toyota. The world’s biggest car company has been perhaps the most openly skeptical of electrification, with leadership arguing time and again against the economic feasibility of electric cars. Public statements make it sounds as if the company is being dragged away from the combustion age against its will. And yet, as the other car companies drift into limbo amid the chaotic current market, here is Toyota, slowly building up something rather than shifting its plans every couple of years.
Though its first true EV, the bZ4x, wasn’t up the standard of today’s best EVs, Toyota has stormed into 2026 with an improved version, the bZ, plus a revival of the C-HR small crossover in fully electric form. Toyota is in the midst of electrifying the Highlander SUV and even rolled out a concept car to tease a battery-powered makeover of the iconic Toyota Corolla. While the rest of the industry retreats from EVs to formulate a new plan, Toyota chose this moment to dive in headfirst. The same is true of its frequent design partner, Subaru, which has finally introduced multiple EVs to join the race.
Compare that with the turmoil at rival Honda. Like Subaru, it borrowed technology to accelerate its entry into the U.S. EV race — in Honda’s case, building the Prologue crossover on GM’s Ultium system. The company put several new EVs in the pipeline that would be Hondas from the ground up. Earlier this year, it killed them all, with leadership convinced its efforts just couldn’t compete, especially in non-U.S. markets where it would go up against the dirt-cheap offerings coming out of China.
Then, of course, there’s Tesla. Elon Musk’s brand is suddenly thriving again, thanks in large part to the vacuum created by the rest of the industry. Tesla, for all its bad press in some corners of the internet, still makes up more than half of EV sales in America, and the numbers soared in Q2 in spite of everything that’s been going on with Musk and his company (his focus on everything else that’s not human-driven cars, his political misadventures, and his reliance on just two aging car models, just to name a few issues).
That legacy car companies have stalled and flip-flopped on electrification as the political winds have changed has left the door open for the other EV-only startups. Rivian’s much-ballyhooed R2 arrived this summer and is off to an excellent start on its mission to make that company mainstream. Slate has finally taken the cover off its affordable electric small pickup. Lucid has been dogged by bankruptcy rumors as it tries to cross the startup’s valley of death, but for now, it’s still chugging.
With the car industry so scattered and disparate on its electrification efforts, it’s hard to know quite what to make of things. We’re a long way from the go-go Biden era, when government incentives for EV production gave automakers the confidence to make proclamations about going fully electric. Back then, it felt like we might be on the cusp of seeing an EV version of just about everything. Now it feels like the United States government is fighting another losing war — this one trying to singlehandedly save petroleum power while the rest of the world moves on.
Electric cars came to America slowly, and then fast. After decades of science experiments and sci-fi promises and Who Killed the Electric Car?, EVs gained a foothold remarkably quickly after the rise of Tesla. Millions of Americans now own one. But the leap from early adoption to mass adoption — which was first delayed by factors like high prices and unease with new technology — has been further forestalled by an antagonistic administration and an industry flailing about it keep up with its whims.
Electrification is coming. But this lull isn’t going away anytime soon.
There‘s a striking amount of agreement across the political system about what the big issues are.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
The country's fastest-growing market for data centers is, for now, frozen. Governor Greg Abbott of Texas announced on Monday that the state’s grid authority should not allow any more data centers to hook up until state regulatory agencies complete an audit of existing projects.
As part of this audit, data center developers will have to disclose the following, according to the governor:
“Any data center project that fails to comply” with the audit “must be denied,” Abbott wrote in a letter to the agencies.
Abbott's freeze isn't quite broad enough to be called a full-on moratorium. As The Texas Tribune noted, data centers that aren’t asking to connect to Texas’ power grid can proceed as planned. But the announcement does mean New York is no longer the only state where the governor is trying to slow down data center development. As my colleague Alexander Kaufman wrote today in Heatmap AM, Texas’s governor has more than a little in common with New York’s chief executive, Kathy Hochul — above all, they’re both running for re-election in November.
Now, as far as data center regulation goes, Abbott's disclosure requirements are pretty weak tea. That’s chiefly because they are, well, disclosure requirements — they don't require that any developer actually changes their behavior, just that they publish data saying what they were going to do in the first place.
Yet his announcement put me in mind of something I've been thinking about for a while: There might be more agreement about data center regulation than we think.
Take Michigan, for instance. The progressive Senate candidate in that state, Abdul El-Sayed (who could very likely win the Democratic primary tonight), has become prominent partly by speaking out about data centers. He was early to the topic, publishing mandatory “terms of engagement” for data center developers back in January, and his own rise has tracked the issue’s rising salience in American politics.
Some of El-Sayed’s recent remarks about data centers have an undertone of surprise, as if he is a little astounded by how prominent the issue has become. “There’s literally not a conversation that I have, not a stop that I make, where data centers and AI don’t come up,” he said last month. As he recently marveled on a campaign stop last week: “People really effing hate data centers.”
He hasn't called for a national data center moratorium, though, as his allies and endorsers Senator Bernie Sanders or Representative Alexandria Ocasio-Cortez have. Instead, his blessedly short document says Michiganders should have a few “rights” when a data center wants to build in their community:
He’s also called for an end to tax breaks for data centers.
El-Sayed is on the Democratic Party's left. Earlier today, a candidate seen as in the party’s center — Iowa gubernatorial candidate Rob Sand — released his own data center plan. It demands the following, at somewhat greater length:
Look — it’s pretty similar to El-Sayed’s list! Sand might be a moderate, and El-Sayed might be a progressive, but it’s hard to see too much daylight between their data center policies.
What’s notable about these policies is what’s not in them. Neither El-Sayed nor Sand would require that data centers be powered by clean energy, as, say, the Wisconsin DSA gubernatorial candidate Francesca Hong has proposed. Neither El-Sayed nor Sand moots a statewide moratorium on data centers, either. And while their proposals would have more teeth, in theory, than Abbott’s audit, the three proposals are interested in the same questions — energy use, water use, physical footprint, and tax incentives.
As we’ve frequently noted at Heatmap, the data center backlash is strikingly bipartisan. Americans of many backgrounds, belief systems, and byways of life agree that the data center boom is becoming a problem. I wonder if there’s more agreement about the solution, too, than we might think.
